I'm pretty sure that last bit was the SkyTram:
"The SkyTram was a sight-seeing glide thing that was suspended by steel cables a few hundred feet above the ground. It traveled from the Cliff House across Sutro Baths to Point Lobos. The Point Lobos end point had a man-made waterfall added to it. The trip across the cable took around 4 minutes and riders had to walk back to the Cliff House.
The SkyTram was shut down on May 1966."
